Study of Telitacicept in Patients With Refractory IgA Nephropathy

February 22, 2023 updated by: Second Affiliated Hospital, School of Medicine, Zhejiang University

A Single-arm, Forward-looking, Exploratory Clinical Study of Telitacicept in Patients With Refractory IgA Nephropathy

The goal of this clinical trial is to explore the effectiveness and safety of Telitacicept in adults with refractory IgA nephropathy.

The main questions it aims to answer are:

  • To evaluate the clinical efficacy of Telitacicept in patients with refractory IgA nephropathy.
  • To evaluate the safety and adverse reaction of Telitacicept in patients with refractory IgA nephropathy.

Participants will be subcutaneously injected with 240mg of Telitacicept once per week.

Study subject: After 6 months of sequential treatment with renin-angiotensin system (RAS) blockers or glucocorticoids, patients with pathological biopsy of 0.7≥5 g/24 hours of proteinuria was confirmed as refractory IgA nephropathy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Complete clinical response
Time Frame: 3-year
a. Proteinuria: protein-to-creatinine ratio <0.2; b. Stable renal function: eGFR decreased by less than 5ml/min/1.73m2 from baseline at the end of the 3-year trial phase.
3-year
The absolute value of eGFR
Time Frame: 3-year
The absolute value of eGFR decreased by more than 15 ml/min/1.73m2 over 3 years from baseline

Changes in 24-hour urinary protein
Time Frame: 104 weeks
Changes in 24-hour urinary protein at week 104 compared with baseline.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
eGFR decrease
Time Frame: 3-year
The estimated glomerular filtration rate (eGFR) decreased by more than 30 ml/min/1.73 m2 from baseline.
